1981-On FIAT DOHC cylinder heads are the most desirable because of improved combustion chamber design and lack of North American pollution control provisions.
This head can be retrofit on any 1800cc or 2000cc Fiat DOHC engine for FIAT 124 Spider / 131 application that does not require pollution control (i.e. air pump, EGR, etc.)
The valves are prepared with competition-level focus to the face and the valve seat, increasing flow significantly over stock. Runners are mildly deburred, and the combustion chamber smoothed.
Beadblasted and cleaned prior to rebuild. Cylinder head face, and cam box mating surfaces are all milled (5 cuts!) with mirror finish to ensure straightness and end those annoying oil leaks. Most shops don't do that. New valve springs, valves, valve stem seals and camshaft seals are used, with stock style intake/exhaust camshafts.
